FLEXIBLE HUB FOR WHLS.

SPECIFICATION forming part of Letters Patent No. 644,730, dated March 6, 1900.

Application filed August 4, 1899.

T0 all whom it may concern:

Be it known that I, SAMUEL COLT, a citizen of the United States, and a resident of Santa Barbara, in the county of Santa Barbara, State of California, have invented a new and useful Flexible Hub for vWheels, of which the following is a specification.

My improvement consists in causing a weight resting upon the axis of a hub to have elasticity or less rigidity. It is effected by the hub acting independently but in confined contact with the wheel, with springs placed between them (fastened in the hub) pressing against a flange fastened inthe wheel. The hub and wheel are sustained in their relation to each other by a central flange fastened to the wheel extending into the hub and bytwo exterior flanges extending outwardly over each side of the hub, between which the hub has space to yield to the pressure of or on the springs. The central flange fastened to the wheel comes in contact with the entire surface of a circular spring fastened in the wheel, which is supported by a circular spring of spiral form. The hub is made in two parts, which when bolted togethercover and hold in place the springs placed in a circular groove with space to allow the springs to yield to pressure.

The mechanism of the hub and wheel is illustrated by the accompanying drawings, in which- Figure 1 is a horizontal View of the hub A Serial No. 726,177. (No model.)

and wheel I, with one-half of the hub A and one exterior iiange B removed, showing the central iiange C in contact with the circular spring D, inclosing the spiral spring E in the circular groove F made in the hub A, also the circular space H in the Wheel I, which permits the hub A to slide in the wheel I. Fig. 2 is a horizontal view of the hub A removed from its counterpart, showing the cir-V cular groove F, which holds the springs E and D in place when bolted in place. Fig. 3 is a View of an exterior fiange B, fastened to the wheel I, which extends over the hub A; Fig. 4, a sectional View of hub A and wheel I, with the dierent parts in place and lettered according to the above description. an exterior View of wheel I and hub A.

Siniilarletters refer to similar parts throughout'the specification.

I claim- In the combination of a hub working inde= pendently of a wheel but held in firm relation to it, a central flange C slidingin the hub two exterior flanges B the circular groove F within the hub the circular spring D the circular spiral spring E the circular space between hub and wheel substantially as described and for the purpose specified.
